The Indexing Cam institutions with a short drive chain, high precision, smooth motion, reliable transposition, transposition and stop times than unrestricted and etc., has become the most widely used in the machinery industry in the cam mechanism, especially in CNC machine tools, automated production lines and other fields increasingly common. However, due to the complex structure, difficult to manufacture, carrying capacity, reliability, service life of domestic indexing cam institutions with similar foreign products is still a wide gap. The lagging manufacturing process has seriously affected the quality, efficiency and application of indexing cam mechanism products. Therefore, carry out the Globoidal Virtual Machining Simulation Technology the Globoidal achieve fast, efficient, high-quality development and production has important practical significance. In this paper, based on UG VERICUT software by describing the different roller the type Globoidal working profile equation, the establishment of Arc Cam multi-axis CNC machining process, established Globoidal multi-axis NC machining simulation program, in order to achieve Globoidal generating method and tool position offset method of multi-axis CNC machining process simulation test. Specific research work are as follows: 1) Summary of indexing cam institutions basic theory, the machining simulation Globoidal research status and problems, arc cam roller type work profile equation systematically expounded, while establishing the Arc Cam generating method and tool position offset method multi-axis CNC machining process. 2) to establish the multiaxial virtual machining Globoidal simulation environment. UG and VERICUT software related parts and components of the three-dimensional solid models, including arc cam parts, blanks, knives, five-axis machining center machine for the processing Globoidal DMU80T simplified entity model. 3) completed the different roller type Globoidal in generating method and tool position offset method automatic programming of multi-axis CNC machining. Concrete application of UG software toolpath planning to generate cutter location file, and use of UG / the Post Builder realize the the DMU80T five-axis machining center custom post-processor, generated NC programs available for machining simulation test. 4) Arc Cam generating method and tool position offset method multi-axis CNC machining process simulation test. VERICUT software for different types of roller Globoidal generating method and tool position offset method multi-axis CNC machining process simulation, you can check the tool path and processing parameters are correct and reasonable, the processing whether there is interference, excessive cutting anomaly Globoidal before actually machining, multi-axis CNC machining process can be effectively complete inspection. In summary, this study for Globoidal achieve fast, efficient, high-quality development and production provides an effective platform based on the UG VERICUT globoidal multi-axis NC programming simulation, to further improve the multi-axis CNC machining process of the globoidal .
